Title: Radiographic apparatus
Inventor: GRAVES EDWARD BORCHARD
IPC: G21K1/02
Filed: 1951-09-21
Abstract: 693,475. X-ray apparatus. PICKER X-RAY CORPORATION, WAITE MANUFACTURING DIVISION, Inc. Sept. 21, 1951, No. 22183/51. Class 98 (i). In radiographic apparatus including a cassette for film to be exposed to an X-ray tube, and means for smoothly moving a Bucky grid between the tube and the cassette, means being provided for holding the grid in a pre-set position before an excursion thereof, the holding means are associated with electrically-operated release means therefor connected in a series circuit with a make-and-break device closed by inserting the cassette into the apparatus, and a switch closed by pre-setting the grid. As shown, an X-ray cassette 12 is held between jaws 13, 14 slidably mounted on a tray fixed under an X-ray examination table. A Bucky grid 18 is mounted for sliding movement by means of brackets 19 sliding on rods 20 mounted on a frame 17 fixed under the table, and ears 22 sliding in a portion of the frame 17. To prepare the grid for an excursion, it is drawn against action of springs 23 until a projection 24 on the grid engages a latch 25. The speed of the grid, when released and moving under action of the springs, is regulated by means of a dashpot device comprising a piston 32 connected to the grid and moving in a cylinder 31 mounted on frame 17 and containing liquid passing through conduits 36, 38 and a flexible bellows 37, the rate of flow being controlled by a needle valve 41. The cassette clamping jaw 13 has a switch 44 which is operated only when the cassette is properly in position. Switches A, B, C are mounted on the frame 17 and operated by a lug 50 on the grid 18, the arrangement being that when the grid is in its latched position, switch B is open, lug 50 holds switch C closed, and a projection on the operating lever of switch C holds switch A open. An electrical circuit includes a push-button switch, contacts operated by switch 44, and switch C. When the button is pressed, provided that the grid is latched, closing switch C, and that the switch 44 contacts are closed, a solenoid 30 is energized, operating the latch and releasing grid 18, and simultaneously energizing a contactor which switches on the X-ray tube. As the grid begins to move, switch C opens, but not until an alternative circuit for the tube contactor has been made through switch A, which is now closed, and switch B. The button can now be released, de-energizing solenoid 30. At the end of its travel, the grid opens switch B, de-energizing the X-ray tube. The tube cannot be re-energized until the grid has been returned to its latched position. If the cassette is improperly placed in the jaws 13, 14, the contacts of switch 44 do not close and the tube cannot be energized, but if the cassette is removed altogether a second set of contacts of switch 44 are closed, providing a circuit whereby the tube can be energized by pressing the button irrespective of the position of the grid. alternatively, switch 44 may be replaced by a switch which closes only when the cassette is properly in position.

Filed: 1952-09-10
Abstract: The invention comprises an acetylenic carbinol of the formula <FORM:0742868/IV(a)/1> wherein R and R1 represent alkyl radicals and the preparation thereof by reacting an acetal of acetoacetaldehyde with acetylene or an acetylide.  Subsequently the acetylenic carbinol may be reacted with the aldehyde 2-methyl-4-(2,6,6-trimethyl cyclohex-1-enyl)-buta-2-ene-1-al to form an acetylenic 3,6-diol acetal which may be partially hydrogenated to the corresponding olefinic 3,6-diol acetal.  The olefinic 3,6-diol is converted to Vitamin A aldehyde by subjecting successively to dehydration, hydrolysis by means of an ionizable acid and treatment with a basic catalyst or alternatively the reaction may be effected in a single step with a mixture of organic base and ionizable acid.  Vitamin A alcohol is obtained by subjecting the olefinic 3,6-diol acetal successively to dehydration, hydrolysis by means of an ionizable acid and treatment with a basic reducing agent.  The dehydration of the 3,6-diol acetal may be effected by means of a phosphorus halide or oxyhalide, preferably in the presence of an amine.  Examples describe the production of Vitamin A aldehyde and Vitamin A alcohol starting from 2 - methyl - 4 - (2,6,6 - trimethyl cyclohex - 1 - enyl) - buta - 2 - ene - 1 - al.

Title: Improvements in the manufacture of cellulose acetate textile materials
Inventor: HILL FRANK BRENTHALL
IPC: D01F2/28
Filed: 1954-08-05
Abstract: Cellulose acetate filaments, yarns, fabrics and other textile materials, in the production of which an acetone solution of cellulose acetate has been wet-spun into a coagulating bath comprising a solvent for the cellulose acetate diluted with sufficient water to render it a non-solvent, are given a uniform lustre by treatment with an alcohol containing up to four carbon atoms in the molecule, especially a monohydric alcohol completely miscible with water, preferably ethyl alcohol.  The coagulating bath is preferably aqueous acetone or aqueous diethylene glycol diacetate. The alcohol may contain water or other substances, but these should preferably be neither solvents nor strong swelling agents for cellulose acetate, and the treating liquid should contain at least 80 per cent and preferably at least 85 per cent by weight of the alcohol.  The material may be treated at any stage after the actual spinning operation.  For example, a freshly spun yarn may be washed with the alcohol at 20-30 DEG  C. to remove coagulating liquid from it, or a yarn which has already been washed may be treated before or after it is dried.  A fabric may be treated before or after it is dyed or otherwise finished.  The textile material is preferably treated at above about 30 DEG  C. but not above about 60 DEG  C., e.g. ethyl alcohol is best used at about 45-55 DEG  C.  The duration of the treatment may be from a few seconds to 15 minutes or more.  In an example a 60-denier cellulose acetate yarn, which has been formed by extruding an acetone solution of cellulose acetate into 34 per cent aqueous diethylene glycol diacetate at 34 DEG  C. and drawing the yarn at 40 metres per minute over a friction device to wipe off adhering coagulant, is forwarded to a washing device comprising a pair of mutually inclined thread-advancing rollers.  The yarn makes a total of 60 wraps round the rollers, and industrial spirit at about 50 DEG  C. is applied at a rate of 5 litres per minute to the upper end of the lower roller.  The yarn, after leaving the washing device, is at once dried by passing it round a pair of heated thread-advancing rollers.  Specifications 720,187, 787,556, 787,557, 787,558, 787,559, 787,560, 787,561, 787,562, 787,563 and 787,564 are referred to.
